oeqa/selftest/cases/devtool.py: avoid .pyc race

In certain conditions, most likely under heavy load on the
AutoBuilder, the prebuilt .pyc files are attempting to be
executed before they have been completely copied. Avoid
this by not copying the .pyc files (nor the __pycache__
directory). The impact of python3-native recreating the .pyc
files should hopefully be negligible.
